Yep, those are both options, the catch is how much work you want to put into it. In terms of your first question/option, it's pretty straight forward since you're only having to connect two leads. If you're good with soldering and have some shrink tubing, it's pretty straight forward so long as you do a good job and have a strong contact to make sure the cable isn't left too thin or with weak contacts. The only part I don't know is if introduces any interference / distortion on the analog outputs since that part of the cable may not be insulated as well. My guess is that the answer is "no, it's fine", since that's the input power portion of the chain rather than something downstream, plus, that's something that would literally affect all other power methods (substitute PSU, USB, etc.) so I doubt it's material in terms of impact, but something I had thought about. If using the digital outs then it's definitely a non-issue. On the second question/option, same thing, I would imagine it's perfectly possible, just more work and you risk doing damage to the actual receiver (that costs more than a cable) plus have to retrofit it into the case/hole that was smaller originally. A third option I've been contemplating that would solve a lot of these problems but I haven't come across as I'm not that much of a electronics person (so I'm not sure if it exists), is if there is any such thing as a brass insert ring to extend the outer diameter of any barrel plug. Really, all we need is to maker the outer diameter of the 3mm x 1.1mm plug a little bigger an a lot of problems would be solved. I also say brass because that's what barrel plugs are made of to my knowledge. If there was such a thing, then such an insert ring could be added to the 3mm barrel plug size to oversize the outer diameter to 3.5mm or 4mm and then you'd have a snug fit on the inner and outer diameter (the 3mm plug is 1.1mm on the inside). But alas, I have not come across any such thing. ------------------------------------------------------------------------ -Axle-'s Profile: http://forums.slimdevices.com/member.php?userid=40475 View this thread: http://forums.slimdevices.com/showthread.php?t=117298 _______________________________________________ Duet mailing list [email protected] http://lists.slimdevices.com/mailman/listinfo/duet
